Just another oil to consider.

I loved Castrol Syntec 20w50, just can't find it anymore.

The Castrol folks have a new oil line for consideration, Edge 5w50.

From them:
The specific amount of zinc in Castrol EDGE with Syntec Power Technology SAE
5w-50 is considered proprietary however we can advise you that it contains a
minimum level of 0.13 or 1300 ppm.

I just filled both the 6kw troll and the bbo.

The bottle actually says for flat tappet engines.

I have been using Mobil 1 "15W- 50" I can not find it anymore. They
have high mileage version "10W-40" API SL. Is this a good oil to use
in my engine?? I would also like to change the Transmission Oil with
synthetic. What would you guys recommend? How much trans oil should I
get? I was going to try Larry's method to change all of it. All help
is appreciated.

If they have it in Ypsi, then it must be at the warehouse (5 miles north of me) so any O'Murray's should be able to bring it in.

Gary,

Here's what Manny recommends:

http://tinyurl.com/3wk5ehz

http://www.mobiloil.com/usa-english/motoroil/other_products/mobil_1_syntheti
c_atf.aspx

I bought it at AutoZone; however, I just went to their website and it's not
listed.

It is fully compatible with "normal" transmission fluid; however, you will
not be able to change it all to synthetic as fluid in the torque convertor
will not be changed.

Below is the procedure Larry Weidner has used successfully to change it all.

Regards,
Rob M.

*************************************************************************

Rob,

You can take it to a "Jiffy Lube" type place to have them change the fluid,
and to my way of thinking that is the only way to *completely* change all of
the fluid, as long as you have the filter changed also. The only catch is,
the last couple of times I stopped at a "Jiffy Lube" type place, they were
*not* offering synthetic fluids as a change option. So you may have to make
a sort of deal with the owner/manager to use synthetic fluid. That being
said, you can get most of the oil out using the following procedure. Keep
in mind, there are several (perhaps many) that would not do this. (including
IIRC Manny). I've done it many times with no ill results.

Sooooooo.....

This is a very messy procedure; you're gonna spill fluid, so be prepared
with dry rags and the like to clean-up afterwards.

1. Do this with the trans cold. Wait at least over night.
2. Raise the coach high enough to get a 5 gal pail under it with room to
spare.
3. Disconnect both trans lines at the radiator, and be prepared to catch the
fluid coming out of the cooler in the radiator.
4. Attach hose extensions to the lines and drop the lines into the 5 gal
pail.
5. Using two people, start the motor for only couple of seconds. Do this to
identify which line the fluid will come out of. Now you know which line you
*must* keep in the bucket.
6. Again, using two people, (one to run the motor, the other to watch the
fluid) start the motor.
7. Run the motor until the fluid line begins spurting air. Shut motor off
immediately! The fluid will get quite frothy.
8. Allow to stand without the motor running for 4-5 minutes. This will let
excess fluid in the trans drain down into the pan.
9. Start the motor again for no more than 5 seconds. Shut off the motor.
This will pump out that last little bit in the pan and make dropping the pan
a lot less messy.
10. Let the oil lines drip into the pail while you drop the trans pan.
11. Drop the trans pan, and replace the filter using two (2) "O" rings at
the filter.
12. Hook up the two trans lines to the oil cooler at the radiator.
13. Fill the trans with about 7 quarts of trans fluid.
14. Start the motor and allow to idle for about 30 seconds or so before
checking fluid level.
15. Check fluid level and add accordingly.
16. Once full, drive until normal operating temp is reached, and recheck
fluid level. Add fluid to bring to "Full".

I've used this procedure on every auto trans that I've owned for .... well
.... forever.

This is just the way I do it....your mileage may vary.

Just my relatively informed, off the cuff, back yard mechanic, gut level,
eyeball it up and guesstimate, way of doing things....that's all...

Unless you are breaking in a new cam, the whole ZDDP anxiety has pretty well been debunked.

The O'Reilly's in my neighborhood only had it in 1 quart bottles. They
could get me a case of it. It has gone up in price. I used to get the 5
quart jugs at Wal Mart. I have not seen it there for some time now. I
guess I will have to find a replacement. What do you use??

Talk to the manager at Walmart. They should be able to order in a case for you.
